## What you would see

A top-down, almost abstract image with no horizon or sky, filling the entire frame with a mountain range seen from space. Across the upper center stretches a broad, bright white mass of snow and ice, with irregular edges, a rough texture, and patches of bluish-grey shadow. From it, several long, narrow, grey glacial tongues descend toward the center and lower part of the image, lodged in deep valleys like rivers of stone. Two elongated lakes stand out for their intense turquoise: one vertical, in the lower center, and smaller ones toward the right and left, contrasting with the earthy tones. The rest of the terrain is a dense web of ridges, slopes, and drainages branching like veins or roots. Burnt reds and browns predominate — in this kind of image they usually correspond to vegetation — mixed with dark greys, ochres, and black on rocky and shadowed areas. In the upper left corner and in scattered bands appear low, cottony, pinkish-white clouds that partly hide the surface. There are no people, buildings, or scale references; only the repetition of valleys and peaks suggests the enormity of the relief. The light is even, without dramatic shadows, as in daytime satellite observation.

## How to look at it

Start with the great white mass at the top and follow the grey glacial tongues downhill, as if they were rivers. Then find the turquoise lakes: they mark where the ice ends and meltwater gathers. Finally, look at the red branching valleys and the clouds in the upper left, which are easy to confuse with snow.

## Context

According to the source, this image was created by NASA/METI/AIST/Japan Space Systems and the U.S./Japan ASTER Science Team, credited to NASA/JPL and dated March 9, 2017. It was obtained from NASA's Terra spacecraft and covers an area of 39 by 46 km at 43.7 degrees south, 170 degrees east, in the Southern Alps of New Zealand's South Island. The source states that New Zealand has more than 3,000 glaciers, most of them in this range, and that they have been retreating since 1890, with short periods of minor advance. The specific names of the glaciers shown are not given in the source.

## Curious detail

Surprising visual observation: the most intensely colored features are not the glaciers, but the small turquoise lakes, whose color stands out sharply against the red and grey of the mountain valleys.

## Questions

- How does the reading of this landscape change when we remember that each grey tongue is moving ice, not rock?
- What can satellite images show about climate change that a ground-level photograph could not?
- Without people or buildings for scale, how do we imagine the true size of these mountains and lakes?

## Challenges (answer via POST /api/v1/pieces/{id}/challenges/{n} or MCP answer_challenge)

1. What technical type of view is this, with no horizon or sky, taken from the Terra spacecraft and covering 39 by 46 kilometers?
2. In the upper left corner of the image there are fluffy whitish and pinkish patches partly covering the ground, what are they?
